Deploying to Gigalixir not working

charlesjavelona

Deploying to prod on gigalixir shows: {"errors":{"detail":"Not Found"}}
No node for static files. It’s all API based.

When it’s delivered to dev it works.

$ - mix phx.server

[info] Running BujiWeb.Endpoint with cowboy 2.9.0 at 0.0.0.0:4000 (http)
[info] Access BujiWeb.Endpoint at http://localhost:4000

When it’s delivered to prod it doesn’t work

$ - MIX_ENV=prod mix phx.server

23:02:10.310 [info] Access BujiWeb.Endpoint at http://${APP_NAME}.gigalixirapp.com:443

Any idea on why cowboy doesn’t show IP on prod? It crashes.

config/prod.exs

use Mix.Config

config :buji, BujiWeb.Endpoint,
  server: true,
  http: [port: {:system, "PORT"}], # Needed for Phoenix 1.2 and 1.4. Doesn't hurt for 1.3.

config :buji, Buji.Repo,

Any idea on why cowboy doesn’t show IP on prod?

It does show it, but it’s using ipv6 where zeros are ommited, :::4000, means it binds on all interfaces. I haven’t used gigalixir, but if I were you I’d double-check if ${APP_NAME}.gigalixirapp.com is interpreted correctly by gigalixir, since it seems like it’s not, otherwise it would’ve been replaced with env vars at

By default neither phoenix nor elixir config support env var templates like this.

Where did you run above cmd?

Could you post all gigalixir log here, there must be more information about the error.

This is what the doc says, but it seems outdated. Will try a different way.

The above command is ran locally to test prod environment. Prod log is below. Most recent.

# ## SSL Support
#
# To get SSL working, you will need to add the `https` key
# to the previous section and set your `:url` port to 443:
#
#     config :buji, BujiWeb.Endpoint,
#       ...
#       url: [host: "example.com", port: 443],
#       https: [
#         port: 443,
#        cipher_suite: :strong,
#         keyfile: System.get_env("SOME_APP_SSL_KEY_PATH"),
#         certfile: System.get_env("SOME_APP_SSL_CERT_PATH"),
#         transport_options: [socket_opts: [:inet6]]
#       ]
#
# The `cipher_suite` is set to `:strong` to support only the
# latest and more secure SSL ciphers. This means old browsers
# and clients may not be supported. You can set it to
# `:compatible` for wider support.
#
# `:keyfile` and `:certfile` expect an absolute path to the key
# and cert in disk or a relative path inside priv, for example
# "priv/ssl/server.key". For all supported SSL configuration
# options, see https://hexdocs.pm/plug/Plug.SSL.html#configure/1
#
# We also recommend setting `force_ssl` in your endpoint, ensuring
# no data is ever sent via http, always redirecting to https:
#
#     config :buji, BujiWeb.Endpoint,
#       force_ssl: [hsts: true]
#
# Check `Plug.SSL` for all available options in `force_ssl`.

# Finally import the config/prod.secret.exs which loads secrets
# and configuration from environment variables.
import_config "prod.secret.exs"

This is what works for me:

config :testivator, TestivatorWeb.Endpoint,
  http: [port: {:system, "PORT"}],
  load_from_system_env: true,
  cache_static_manifest: "priv/static/cache_manifest.json",
  check_origin: ["//testivator.com"],
  force_ssl: [rewrite_on: [:x_forwarded_proto]],
  live_view: [signing_salt: System.get_env("AUTHENTICATOR_SEED")]

I also have releases.exs

config :testivator, TestivatorWeb.Endpoint, server: true

So, I rewrote everything to release.exs.
Same problem

To give context, I don’t have webpack. Purely using elixir for API. The root url shows this in local dev

If I use local dev to connect to the API it works. But in prod it doesn’t. Anything else I should try I’ve exhausted 3 of the options to deploy(release, mix, distillery). It must be something I’ve done because it’s only API based. I tried the getting started with webpack and it works.

Post #8

charlesjavelona

Here’s an update, since I ran the command below to only have API’s.
mix phx.new ~/Workspace/hello_world --no-html --no-webpack

I thought deleting the Plug.Static would change things in /lib/APP_NAME/APP_NAME_WEB/endpoint.ex. The section below was deleted since I don’t need it.

 # Serve at "/" the static files from "priv/static" directory.
  #
  # You should set gzip to true if you are running phx.digest
  # when deploying your static files in production.
  plug Plug.Static,
    at: "/",
    from: :buji,
    gzip: false,
    only: ~w(css fonts images js favicon.ico robots.txt)
